Answer 1

The coordinates of vertex A', vertex B' and vertex C' are (-8, 4) , (-12, 12) and (-4, 12) respectively.

Explanation

According to the given diagram of triangle ABC, the co ordinates of the vertices are: $A=(-2,1), B=(-3,3)$ and $C= (-1,3)$

If triangle ABC is dilated by a scale factor of 4 to form triangle A'B'C' , then we need to multiply each co ordinate by the scale factor of 4.

So, the co ordinate of A' will be: $(-2*4, 1*4)=(-8,4)$

the co ordinate of B' will be: $(-3*4, 3*4)=(-12,12)$ and

the co ordinate of C' will be: $(-1*4, 3*4)=(-4,12)$
